I've searched for this and I'm still not too sure on how to do it, so I wanted to make sure I've got this down pat. I'm currently on my Windows XP machine where ALL of my files are stored. I purchased a Seagate GoFlex external hard drive. Yay. It's in NFTS and includes the drivers so my new MacBook Pro (ordered today, headed my way soon) will be able to read it and write to it. I have heard that the best thing to do is format it to FAT32. However, when I go to format it on my Windows machine, the only options are to format it to FAT64... not what I want. From what I've read on the internet, Windows can't format a drive this large into FAT 32 and that I'd need to download some sort of program to do it ((saw that on this link). Is this true? Is that what I need to do? I will need to be able to use this drive on both a PC and a Mac. I don't want compatibility issues which I've heard can happen if I leave it in NFTS. Help me. I'd like to go ahead and move all of my files onto the drive ASAP... Thanks for any and all help!
